a1ac77877f Add a method to determine if the coordinate operation string returned 
by QgsCoordinateTransformContext.calculateCoordinateOperation corresponds
to the reverse of what's actually required.

Gross API, but it's the best we can do until proj has a method to
invert a coordinate operation so that we can return the proper
inverse operation proj string from calculateCoordinateOperation
(without resorting to fragile proj string parsing/mangling)

ef19797997 Add method to retrieve the details of the coordinate operation which is 
actually being used by a QgsCoordinateTransform object

82a84ffd0d Don't try to normalize proj coordinate operations constructed directly 
from the proj string via the transform context

This isn't possible -- only proj coordinate operations constructed
from a src/dest CRS pair can be normalized, not those constructed
from a proj string.

It was redundant in any case, since we always normalize the available
operations before giving users a choice of them.

So just add some big bold warnings to the dox in case anyone is
manually manipulating and adding custom operations, that these
also MUST be pre-normalized

8de83c5133 When saving and restoring CRS definitions to XML, save wkt 
definition too, and prefer rebuilding the CRS from the WKT
definition whenever it's available

Proj strings are lossy, so prefer WKT

Fix compilation error in qgsdxfexport.cpp 
I'm not sure which of QT 5.9.0 or gcc 5.5.0 is not happy, but with both
of them, I get:
```

187b8f3325 When saving a user crs, if a WKT representation of the CRS is available, 
then store and save that

Proj string representations of CRSes are lossy, so we should always prefer
WKT when it's available

b1bbc8511b [labeling] Move settings related to removing labels (e.g. max no 
of labels, min size for labels) to a new class QgsLabelThinningSettings

This new class is designed to contain settings related to how the label
engine removes candidate label positions and reduces the number of
displayed labels.
